ABSTRACT
Endophytic bacteria can play an important beneficial role in plant metabolic and physiological processes, such as binding of free nitrogen phosphate, solvens ,hormone supply and others. From previous research it has been found that endophytic bacteria AGBE3.1TL isolate is the best increase the growth of chili seedling. Stability maintenance of the endophytic bacterial AGBE3.1TL during storage is needed through formulation. The research aimed to obtain a stable formula of endophytic bacteria AGBE3.1TL isolate to the growth of chili seedling. The study was a completely randomized design with 24 treatments and three replicated. The study consists of 2 stages: 1) Optimization of the ingredients composition of endophytic bacteria formula, and 2) Stability of endophytic bacteria formula to growth of chili seedling. The AGBE3.1TL endophytic bacteria formula was introduced by lubricating the seeds and seedling’s roots of chili for 15 minutes. The parameters were observed: viability of endophytic bacteria formula AGBE3.1TL and seedling growth. The results showed that viability of endophytic bacteria formula AGBE3.1TL was stable until 6 weeks of strorage. The best formula for increas the chilies growth is the bran + bagasse stored for 2 weeks .
Key words : endophytic bacteria, plant growth booster, chili, formulation
